El-P said they weren’t planning on releasing the song yet, but time felt just right to do it. The song was included in the group’s third album Run the Jewels 3.

What have the artists said about the song?

for our friends. for our family. for everyone who is hurting or scared right now. here is a song we wrote months ago. we werent planning on releasing it yet but… well it feels right, now. it’s about fear and it’s about love and it’s about wanting more for all of us. it’s called “2100”. we hope it finds you well.

What exactly does the title, 2100, signify?

With the song’s lyrics, it can be seen that the song is talking about present issues, while also talking about issues to come. For example, you have lyrics talking about the present such as the opening line with: “How long before the hate that we hold, lead us to another Holocaust?” while you also have a line such as, “It is wartime, check your wrist, ready kids?” which leave everything open ended, and don’t indicate if it’s past, present, or future. In this case, I think it’s safe to assume that the name “2100” is actually about the year 2100 CE.
